What should I look for in a used Hyundai Coupe coupe?
A five-year warranty as standard means that Hyundai owners are very well looked after, and they're a happy lot as far as the Coupe is concerned, because they report very few faults with the car.
The mechanical components are tough and reliable, so expect no problems from them. Where you may experience some minor trouble is with the electrics, which have been known to suffer from the odd gremlin such as an electric window not working, sunroofs sticking and warning lights coming on for no reason. These faults should have been dealt with under warranty, so used buyers can buy with confidence.
Otherwise, the only things to look for are the usual signs of a careful owner and a complete service history.
